fingers, said deliygery therefore located at the same end of the Ina-- chine where the envelops can be conveniently handled.

What. I claim is 1. In an envelop feeding mechanism, the combination of means for supportinga supply of envelope, means to engage beneath the flap of an envelop and push said envelop into printing position, and means to engage an exterior edge of the envelop and pull said envelop away from printing position.

- 2. In an envelop feeding mechanism, the combination of means for supporting a supply of envelops, fingers adapted. to engage the flap of the first envelop in the supply and feed it forward to printin position, other fingers longer than thefeeding fingers and movable conjointly therewith adapted to engage the envelo after the printing operation is complete and deliveriit and move it away from printing position in a direction beneath the supply.

3. In an envelop feeding mechanism, the combination of means for supporting a supply'of envelops, a frame, means for oscillating the frame, fingers carried by the frame adapted to engage the flap of the first envelop in the supply and feed it forward to printing position, and other means carried by the frame to engage theenvelop after the printing operation is completed and move it rearward awayfrom printing position in a direction beneath the supply.

4. In an envelop feeding mechanism the combination of means for supporting a supply of envelops, a frame, means for oscillating the frame, fingers carried by the frame to engage the flap of the first envelop in the supply and feed it forward to printin position, delivery fingers carried by the rame and movable conjointl with the feeding than the feeding fingers and adapted to engage the envelop on the rearward movement of the frame, and means for holding the envelop in substantially fixed position to enable the feeding fingers to move out of operative cngageu'icnt therewith before the delivery fingers engage the envelop.

In an envelop feeding mechanism, the combination of spring fingers for feeding the envelops from a supply to'pri'nting position, and spring fingers conjointly mov-- able with the feeding fingers but operable on 'tho envelop independently of the feeding fingers to deliver the envelop after it is printed. I

(3. In an envelop feeding mechanism, the comhination of spring fingers for feeding the envelops frornta supply to printing position, spring fingers conjointly movable with the feeding fingers but operable on the envelop independently of the. feeding fingers to deliver the envelop after it is printed, and

ngers being longer,

means for holding the envelop in fixed position to enable the feeding fingers to move out of operative engagement therewith before the delivery fingers move into operative engagement therewith.

, '7. In an envelop feeding mechanism, the

combination of spring fingers for feeding the envelops from a supply to printing posi tion, spring fingers conjointly movable with the feeding fingers but operable on the en.-

.velop independently of the feeding fingersto deliver the envelop after it is printed, means for holdingthe envelop in fixed position to enable the feeding fingers to move out of operative engagement therewith before the delivery fingers move into operative engagement therewith, and means for adjusting said holding fingers for envelops of different widths.

8. In an envelop feeding mechanism, the combination of devices for feeding the en velops from a supply to printingposition, delivery devices 'conjointly movable with the feeding devices but operable on the en velop independently of the feeding devices, and a face plate on the machine for guiding the envelop and the feeding and delivery v devices.

9. In an envelop feeding mechanism, the

position, and means for engaging said en-' velop at the flap edge exteriorly of the flap and removing said envelop flap edge'last from printing position.

10. In an envelop feeding mechanism, the combination of a movable member, an envelop feeding device mounted thereon and adapted to engage an envelop beneath the flap thereof, and a delivery .device mounted on said movable member to engage with the envelop after the feeding device has been released therefrom and remove said envelop from'printing position.

- 11. In an envelop'feeding mechanism, the combination 'of'a movable member, a device carried thereby and adapted to engage beneath the flap of an envelop and feed said envelop to printing position, and a' device carried by said member and adapted to engage the fi'ap'edge of said envelop and re move the envelop from printing position.

12. In an envelop feeding mechanism, the combination of an oscillatory member, an envelop feeding and an envelop removing device each mounted on said oscillatory member, and means for actuating said mem bcr whereby an envelop is fed fiap edge foremostby said feeding means to printing position and subsequently removedflap edge rearmost from printing position.

1.8. In an envelop feeding mechanism, the combination of an oscillatory member, a spring finger carried thereby in position to H. R. DI'H'JKELR.
